Question

factorise:2x2 + y2 + 8z2

- 2√2 xy -24yz -16xz​

Answer 1

check the solution below

Step-by-step explanation:

if a =‐root2x,b=yandc=2root2z

then using the identity

(a+b+c)²

we get

2x²+y²+8z-2root2|xy+4root2yz-8xz(-root2x+y+2root2z) (-root2x+y+2root2z)

=(-root2x+y+2root2z)²

ur answer
